Airborne observation of CO2 mixing ratio in the Arctic troposphere and lower stratosphere
Tropospheric and lower stratospheric CO2 mixing ratios were measured onboard an aircraft in the Arctic Airborne Measurement Program 1998. Steep vertical gradients in CO2 mixing ratio were observed in the lower stratosphere. Small gradients were seen in the troposphere, reflecting weak sources and si...
